Synopsis

rebuildCurve( curve [curve] , [caching=boolean], [constructionHistory=boolean], [degree=int], [endKnots=int], [fitRebuild=boolean], [keepControlPoints=boolean], [keepEndPoints=boolean], [keepRange=int], [keepTangents=boolean], [name=string], [nodeState=int], [object=boolean], [range=boolean], [rebuildType=int], [replaceOriginal=boolean], [smartSurfaceCurveRebuild=boolean], [spans=int], [tolerance=linear])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

rebuildCurve is undoable, queryable, and editable.

This command rebuilds a curve by modifying its parameterization. In some cases the shape may also change. The rebuildType (-rt) determines how the curve is to be rebuilt. The optional second curve can be used to specify a reference parameterization.

Return value

string[] Object name and node name

In query mode, return type is based on queried flag.

Flags

caching, constructionHistory, degree, endKnots, fitRebuild, keepControlPoints, keepEndPoints, keepRange, keepTangents, name, nodeState, object, range, rebuildType, replaceOriginal, smartSurfaceCurveRebuild, spans, tolerance
Long name (short name) Argument types Properties
fitRebuild(fr) boolean createqueryedit
If true use the least squares fit rebuild. Otherwise use the convert method.
Default: true
rebuildType(rt) int createqueryedit
How to rebuild the input curve. 0 - uniform, 1 - reduce spans, 2 - match knots, 3 - remove multiple knots, 4 - curvature 5 - rebuild ends 6 - clean
Default: 0
spans(s) int createqueryedit
The number of spans in resulting curve Used only if rebuildType is uniform.
Default: 4
degree(d) int createqueryedit
The degree of the resulting curve 1 - linear, 2 - quadratic, 3 - cubic, 5 - quintic, 7 - heptic
Default: 3
tolerance(tol) linear createqueryedit
The tolerance with which to rebuild.
Default: 0.01
endKnots(end) int createqueryedit
End conditions for the curve 0 - uniform end knots, 1 - multiple end knots,
Default: 0
keepRange(kr) int createqueryedit
Determine the parameterization for the resulting curve. 0 - reparameterize the resulting curve from 0 to 1, 1 - keep the original curve parameterization, 2 - reparameterize the result from 0 to number of spans
Default: 1
keepEndPoints(kep) boolean createqueryedit
If true, keep the endpoints the same.
Default: true
keepTangents(kt) boolean createqueryedit
If true, keep the end tangents the same.
Default: true
keepControlPoints(kcp) boolean createqueryedit
If true, the CVs will remain the same. This forces uniform parameterization unless rebuildType is matchKnots.
Default: false
smartSurfaceCurveRebuild( scr) boolean createqueryedit
If true, curve on surface is rebuild in 3D and 2D info is kept
Default: false
Advanced flags
caching(cch) boolean createqueryedit
Modifies the node caching mode. See the node documentation for more information.
Note: For advanced users only.
nodeState(nds) int createqueryedit
Modifies the node state. See the node documentation for more information.
Note: For advanced users only.
Common flags
name(n) string create
Name the resulting object
constructionHistory(ch) boolean create
Turn the construction history on or off
object(o) boolean create
Create the result, or just the dependency node
replaceOriginal(rpo) boolean create
Create "in place" (i.e., replace)
range(rn) boolean create
Force a curve range on complete input curve
